ENVELOPE.

Application filed October 24, 1921. Serial No. 510,067.

In sending articles by mail, it is often desirable to include firstclass matter, such as an invoice, in the same package with the articleon which a lower-rate of postage is paid, thus eliminating the necessityof mailing two packages and insuring the delivery of both the articleand the invoice at the same time.

A further object is to provide an envelopeadapted particularly formailing motor vehicle license tags, taking a low rate of postage, andincluding in the same envelope the bill or invoice for the tag,requiring first class postage.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a view of an envelope embodying my invention, ready for use,

Figure 2 is a similar view, showing the guiding flap in place,

Figure 3 is a view, showing the small. envelope containing the bill orinvoice inserted into the larger envelope,

Fi ure 4 is a view showing the envelope close and sealed, read formailing,

Figure 5 is a view 0 a first class envelope in which the invoice or billis placed.

In the drawing, 2 represents an envelope havin an open end 3 and aclosing flap 4 there or. Into this envelope the license tag or otherarticle to be sent at a low rate of postage is inserted. Along themiddle portion of the envelope on one side are lapping edges 5 and Ggummed and sealed in the usual manner in making envelopes, The edge 6iscut transversely at 7 .to a point be yond the inner end of the edge 5,forming a flap 8 and a gap 9 between these flaps and the edge 5. Intothis gap an envelope 10 is adapted to be inserted, provided with agummed flap 11 and with an opening 12 through which the name on the nvoce or bill is visible. This envelope'when slipped through the gap 9 willbe within the en-',

velope 2, the wall of which has an opening 13 adapted to register withthe open ng 12 so that the person handling the ma l can easily read theaddress on the invoice or bill, as usual in envelopes provided with thisopening. The envelope 10 may be closed. and sealed or, if preferred, theflap may sealed on the edge 5 of the envelope and then the flap 8 foldedover .and sealed to conceal both the gap 9 and the flap of the smallenvelope beneath. Ordinary. first class postage will then be attached tothe flap 8, while second class or other postage will be put onthe mainenvelope.

I prefer to provide a flap l4: gummed or otherwise secured at one end atthe mouth of the large envelope and adapted to bridge the first classpostage envelope inserted through the slot 9 so that the license tag orwhatever may be inserted into the large envelope will slide easilytherein without being obstructed by the end of the small envelope. I amthus able to make out the invoice necessary and seal the small envelope,and then insert the tag in the large envelope with comparatively littleeffort. Thus I utilize the walls of the large envelope as a pocket forthe small envelope and avoid the necessity of making a separatereceptacle for the small envelope.

Envelopes of this kind as heretofore made have a slit cut in the wall ofthe large envelope through which the first class envelope is inserted.This opening or slit is objected to by the postal department, as othermail often slips into or becomes caught in this slit. In my invention, aflap is provided which positively closes the opening through which thefirst class envelope is'inserted, and conse uently there is no dangerwhatever of ot er mail becoming lodged in the walls of the second classenvelope. When the first class envelope has been inserted and the flap 8sealed, the walls of the outer or second class envelope will be intactand present substantially the same appearance as an ordinary envelope ofthis kind.

I claim as my invention:

1. An envelope adapted to contain an article such as printed matter,having an opening for the insertion of a smaller envelope for firstclass matter, and a guide for directing the lower class article past theen.- velope of the first class article.

' 2. An envelopeadapted to contain an article such as rmted matter,havin an open- 2 mg in lts wa l for theinsertlon o a smaller envelopefor first class matter, and a loose flap arranged within said firstnamed envelope.

and adapted to bridge said smaller envelope and prevent articles fromcatching thereon. 3. An envelope adapted to receive. articles of a lowerpostage rate, such as printed mat.- ter, and having a flap formed in itswall exposing a gap leading into the envelope, and a first classenvelope adapted to be inserted through said gap and concealed edgesbeing slit transversely to form a flap exposing a gap leading into theenvelope and a first class envelope inserted into said first namedenvelope and sealed therein by said flap. 1

5. As a new article of manufacture, an envelope adapted for mailingarticles lower than first class, having a slit in its wall through whichthe body portion of a first class envelope is inserted, the flap of saidfirst class envelope engaging one edge of said slit for holding thefirst class envelope in place, and a flap provided adjacent said slitfor closing and concealing it and con cealing the flap of said'firstclass envelope.

6. An'envelopemade from a single blank and having two opposite walls ofsubstantially uniform size, said blank having two openings one providinga slit and the other providinga window in one wall of the envelope,'anda flap extending from the outside ofsaid wall adjacent the slit and adat,- ed to be secured to said wall of the opposite side of the slit.

7. An envelope having in the face wall thereof a window and a slitadjacent said window, and. a flap formed as an integral part of saidface wall, the flap being'provided with means for sealing the slittedportion therebeneath.

8. An envelope having a single wall provided with a window, a slit and aflap for closing the. slit, the flap being formed by severing a marginaledge portion of thewall inwardly to a point to expose the slit to enableinsertion of mailmatter.

9. An envelope made from a single blank forming two opposite walls ofsubstantially uniform size and having an insert opening, said blankhaving marginal slits adapted to form a flap adjacent to said opening,said flap being non-projecting relative to the edge of the marginalportion in which it is formed and extending inwardly to a point toexpose the opening to enable in- -'sertion of mail matter.

10. An envelope made of sheet material having its face-wall formed withoverlapped portions secured together one portion overlapping the otherfor substantially the full length of theenvelope on the face of theenvelope between the upper and lower edges thereof, one of said wallportions being divided inwardly from its edge to leave an insert openingand provide a flap sub- 'sta'ntially .co-extensive with said opening,said flap having means for-- securing the same to the other wall portionto seal the opening to enable insertion of mail matter 12. An envelopeformed in part of overlapped portions one portion overlapping the otherportion for substantially thefull length thereof on'the face of thee'nvelope between the upper and lower edges thereof,

one of said portions being cut inwardly from the marginal edge thereoftoa point beyond the adjacent edge of the other portion to provide aninsert opening and constitute a'closing flap for said opening non-pro-'jecting relative to the edge of the portion 7 in which the flap isformed. 13. An envelope formed of a single piece of material having afront portion folded over on said out portion, a

supplemental back portion folded over on said first-mentioned backportion across the front of the envelope for substantially the fullwidth thereof and connected thereto but free therefrom for a portion ofits length in a region intermediate the upper and lower edges ofthe-envelope, providing an opening or gap adapted to receive mailmatter, and a sealing flap on said supplemental back portion at leastco-extensive'with said mailreceiving opening at its free portion,adapted to be connectedto said other back'portion.

14. An envelope formed of a single piece of material having a frontportion, a back portion folded over on said front portion, asupplemental back portion folded over on said first-mentioned backportion across the front of the envelope for substantially the fullwidth thereof and connected thereto but free therefrom for a portion ofits length in a region intermediate the upper and lower edges of theenvelope, providing an opening'or gap adapted to receive mail matter,and a sealing flap on one of said back portions at least co-extensivewithsaid mailreceiving opening at its free portion adapt-' ed to beconnected to said other back portion.
